1981 R.L. Mumme Melanerpes formicivorus Hay-Blom (24 April) of bluebirds trying to take over the hole. Unfortunately, [illegible] nobody went into the hole, Mary, watching here after I at 1130 left, reported birds going in, but she saw no egg tossed 25 April Hole checked 1000. Egg is gone!! within 24 hours! N = 3, 26 April Introduce egg at 0700. Watching to try to get photo of "egg-tossing". 0900. Windy, Cold. Bagging it. Leaving a plaster egg in the hole. No birds came to nest while I watched, 28 April Nest check 1000. Plaster egg is (of course) gone. N = 4 (5?) Fake egg was heated out within 48 hours. 7 May After hearing from Mary that Hay Blom birds were not going to the usual nest hole, and that she was seeing only one bird at a time, I come up here at 0700 to see if another nest is about. The answer is unfortunately yes! After seeing ♂173 fly from the granary off to the northwest, I walk around ad see him looking out of a hole in a Valley Oak 50 meters due north of the Big Poison Oak patch, Hole faces the granary, and is the lower of two holes that occupy an upper Branch. Hole is located near a fork. I think the tree can be free climbed, with the help of webbing. 3 Aug Looking for Javs here, 0815. May not be easy, as they have very few acorns remaining, 0910, Forget it. ♂173 or/m and ♀494 Brown-or/Bik Yellow-Blue/Bik born here, the ♀ seen in the granary eating stored acorns. No sign of the javs. 19 Aug Trying again 0820. These birds are now definitely out
